LED electronic display screen should be how to solve the problem of heat dissipation
LED electronic display in the use of the process will produce heat, especially outdoor LED electronic display, because of its use of the environment requires a very high brightness, to be more than 4000CD, so that the occurrence of heat is very large, the actual application, improve the LED electronic display heat dissipation, not only effectively improve the efficiency of the LED electronic display heat dissipation, but also to achieve the role of power saving, more Beneficial to improve the efficacy of LED electronic display service life and to ensure that the LED electronic display display effect, then what are the good methods to enhance the LED electronic display heat dissipation effect, here to do a brief introduction.
1 fan cooling, light shell with short-lived internal high-efficiency fan to enhance heat dissipation, the more commonly used method of this method of low cost, good results.
2 the use of aluminum cooling fins, this is the most common way of heat dissipation, with aluminum cooling fins as a part of the shell to increase the heat dissipation area.
3 thermal conductivity and heat dissipation integration - the use of high thermal conductivity ceramics, the purpose of the lamp shell heat dissipation to reduce the LED high-definition display chip operating temperature, due to the coefficient of expansion of the LED chip and I often metal thermal conductivity, heat dissipation material expansion coefficient difference is very large, can not be directly welded to the LED chip, so as not to destroy the LED electronic display chip of the high and low temperature thermal stress.
5 air hydrodynamics, the use of light shell shape, creating convection air, which is * cost of strengthening the heat dissipation method.
6 appearance of radiation heat dissipation disposal, light shell appearance to do radiation heat dissipation disposal, the simpler is to apply radiation heat dissipation paint, you can use radiation to take the heat away from the surface of the light shell.
7 thermally conductive plastic shell, plastic shell injection molding filled with thermally conductive materials, so as to increase the plastic shell thermal conductivity, heat dissipation capacity.
Visible LED electronic display thermal technology development and progress will be conducive to it saving, environmental protection concept. LED electronic display manufacturers in the LED electronic display production, to improve the LED electronic display heat dissipation methods are varied. Heat dissipation according to the power size and the use of the place, there will be different considerations.
Indoor LED electronic display used in indoor environments, brightness requirements are not high, generally in the 600-1000CD can be, so the heat generated is not large, and in the summer indoor are basically open air-conditioning for the heat dissipation of the screen body has a great benefit; LED transparent screen using light bar design, the flow of heat air natural heat dissipation, and the LED transparent screen is generally indoor installations outdoor viewing, indoor air conditioning also plays a great role in its cooling. Air conditioning also plays a big role in its cooling. Comparison of the need to apply more cooling methods of outdoor LED electronic display, outdoor LED electronic display is generally in the installation, if the area is relatively large will be in the screen body inside the device air conditioning to cool down.
